Improved machine for



UNITEDy STATES PATENT QFFICE.

ISAAC F. YILLIAHS, OF NEV YORK, N. Y.

Specication forming part of Letters Patent No. 33,808, dated November26, 186.1.

To @ZZ whom t may concern:

Be it known that I, IsAAc F. WILLIAMS, of the city, county, and State ofNew York, have invented certain vnew and useful improvements inmachinery for applying docks, ground cork, or other similar substancesto the surface of water-proof fabrics, for the purpose of making what isgenerally known in the trade as felt rubber goods, and I do herebydeclare the following to be a full description of the same.

The nature of my improvements consists, first, in arranging thegumming-table at an inclination of about twenty-live degrees, incombination with a self-adjustable distributing-knife, so that when thesolution of gum is applied to the surface of the fabric the knife-edgewill cause it to flow evenly down- 4ward and laterally over the surfaceof the cloth to prepare it for the application of the flock; secondly,in combining with the revolving flock-duster and case surrounding it asmut-collector, so as to prevent the gummed surface of the cloth beingsmutched by the flock, which has a tendency to gather in masses at thefront sides of the cluster-case and fall in iiakes upon the surface ofthe cloth and thus spot it, as well as to cause it to have an unevennessof surface unlike cloth-finished goods,which these goods are designed torepresent; thirdly, in the improved construction of the iiock or clothbeaters, by combining with them swinging arms or beaters, so as to beatthe under side of the cloth by a sudden blow to cause the flock tobecome more thoroughly set in the wet gum than can be done by fixed armsin the revolving beaters; fourthly, in the improved method of arrangingthe carrying-rollers of the cloth so as to suspend it while under theaction of the beaters, and thereby prevent the cloth from jerking overthe gumming-table and under the edge of the distributing-knife, and thusprevent its being evenly gummed over, and, fifthly, in combining withthe beaters a finishing-brush.

To describe my invention more particularly, I will refer to theaccompanying drawings, forming a part of this specifica-tion, the sameletters of reference wherever they occur referring to like parts.

Figure l is a plan view of the machine.

Fig. 2 is a longitudinal out sect-ion through the line at, Fig. I. Fig.3 is aside elevation of the machine.

Letter A is the frame of the machine, having transversely of the top ofit a gummingtable B. This table is arranged at an inclination of sometwenty to thirty degrees, so as to cause the solution of the gum, whenapplied to the cloth in passing over it, to spread more rapidly andevenly than would be the case if the table were level. Upon this tableis secured a gum-distributer knife C, which rests on the surface of thecloth, and by means of set-screws c2 and a spring c3 on their lower endsis made so as to have a self-adj ustable pressure on the surface of thecloth while distributing the gum over it preparatory to the Hockingoperation.

Letter D is a revolving Hock-sifter having an opening in its face forthe introduction of the lflock and adj usted on suitable bearings d2passing through the sides of a shell or inclosed case E surrounding it.In the front side of this case is cuta throat F, in which is arranged asm ut-collector G, which exten ds into the case till nearly in contactwith the sitter. The object of this arrangement is to collect the massesof flock, which have a tendency to accumulate in the front side of thecase, and by falling upon the surface of the cloth as it enters the casecauses a lumpy and smutched appearance, and thereby impairs theclothlike finish aimed at by the manufacture of this kind of goods.

AH H are two revolving beaters arranged on suitable bearings h2 in thelower portion of the sifter-case, so as to work at thelower side of thecloth to beat or drive the iiock into the Wet solution of gum on itsupper surface. Attached to the periphery of the front beater is aswinging arm h3. The object of this is to give a more sudden blow thanis possible by fixed or stationary beaters, and at the same time, inconsequence of the swinging arm closing upon the face of thebeater-axis, not jerking the cloth, as would be the case if thestationary beaters or arms were of the same diameter as the swinging armis when distended. l

Letter I is a cloth carrying and supporting roller adjusted across theframe of the machine just behind the gum ming-table, and sol as to beslightly above tlie back edge of it. The object of this is to supportthe cloth and prevent the transmission of any drawing or jerking motionof it over the giinuniiig-table in consequence of the action oftherevolving beaters.

Letter .I is a finishing-brush arranged in the back end of thesitter-case, the object of which is to lay the iiber of the iiock andgive a smooth cloth-like finish to the goods.

K is a carrying-roller at the back end Y'of'- the machine, and L arevolving beater whose duty it is to beat off anysuperluous flock thatmay adhere to the gummed surface of the cloth. i'

Letter M is a cloth-roller secured at the front end of the machine inadjustable bearings m2,'having a balance-weight m3 attached to it bymeans of a cord running` over a pulley to equalize the pressure on thecloth as it increases or decreases in quantity on the roller.

Letter N is a carrying-roller, upon which the cloth-roller rests.

Letters P P are carryin grollers over which the cloth passes in going through the machine.

R is the cloth-beam arranged just under the gumming-table and off whichthe cloth unwinds in the operation of Hocking, dto.

Letters S S, &c., are a series of pulleys and belts for operating theseveral .parts of the machine, and T the piece of cloth, as representedby the blue-ink line.

proceed to set forth what MI claim and desire to secure by LettersPat-ent of the United States y l. The arrangement of the gu mining-tableso as to be an incline plane, as hereinbet'ore described, in combinationwith a self-adjust* able gum-distributer, for the purposes hereinbeforeset forth.

2. The use of the throat F and smut-col*- lector G or equivalent devicesin the sifter- -case as a method of preventing masses of falling flockfrom smutching the cloth, substantially as described.

3. The use of swinging arms or beaters h3, in combination with therevolving beaters l-I, substantially as described, and for the purposeshereinbefore set forth.

4. The use of the cloth-tension roller I, in combination with thecarrying-roller K at the back end of the machine, arranged on a linebelow the revolving beaters, While the roller I is arranged on a lineabove the gummingtable, so as to support the cloth on these two points,and thus prevent the blows of the beaters drawing or jerking the clothover the surface of the gumming-table.

5. The combination of the finishing-brush J with the revolving beaters,substantially as described.
